FASTFNEE.

' To all whom it may concern:

poses.

Be it known that l, Louis ARKIN, a citizen of the United States of America, and resident of Boston, in the county of Suflolk and State of Massachusetts, have invented new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to separable fasteners of the general type comprising complemental stud and socket members commonly used as fastening means for garments, gloves, automobile curtains and like pur- The fasteners of this general type heretofore provided, other than those of the so-called sew-on type, are for the most part adapted and intended to be perinanently secured "to the material with'the result that they are very difficult. of removal when, as not infrequently happens, it becomes necessary or desirable to remove the fastener or change itsposition upon the material. Furthermore, special tools and appliances are required for affixing these fasteners to the .material and such tools and appliances are not commonly possessed by, or readily available to, many persons who have occasion to aflix fasteners to material.

It is the object of this invention to provide fastener members of this'general class which can be secured to the material without the employment of special tools or appliances and which can be readily removed from the material when such removal becomes for any reason necessary or desirable, thus providing a fastener adapted for general use by all classes of users.

Referring to the drawings which illustrate certain embodiments of the invention,-

elevation of the fastener member shown in Fig. 6 showing the parts affixed to material and Fig. 9 is a bottom plan view of the fas- Fig. 8.

The fastener member shown in Figs. 1 to 5 inclusive is of usual contour and comprises a dome or casing A and a base plate A having the usual stud-receiving opening. While I prefer the particular socket member shown having the stud-retaining and releasing means within the casing A shown in my copending application for' patent Ser. No. 176,820, it will be understood that the particular stud -retaining and releasing means within the casing are not essential to the present invention and that the socket may be provided with any desired stud-retaining means.

The base plate A is provided with a downwardly extending annular skirt A which surrounds the stud-receiving opening formed by the cars A can freely pass when in one position only so that when said skirt A is passed through said holding plate the' parts can be locked by relative rotary movementthereof as presently to be described. At the side of said opening B the plate B is provided with oppositely disposed slots B adapted to retain the edges of the ears A Tn securing the socket member to material, the member proper and the retaining plate B are disposed on opposite sides of the material and the skirt A with its ears A is passed through the material into and completely through the opening B of the plate B. The socket and plate are then relatively rotated 90 from the position shown in Fig. 1 to the position shown in Figs. 41 and 5, whereupon the ears A forming the locking head are moved to a position transverse of the opening B so that the parts are locked and yieldingly held in locke trance of the edges of the ears A into the slots F.

relation by en- To remove the socket member, the member proper and its retaining plate B are pressed toward each other until the edges of the ears A -leave the slots B permitting relative rotation of the plate and socket member to a position 90 from locked position, the skirt A with its locking head being then free to pass out of the opening B.

Referring now to the stud member shown in Figs. 6 to 9 inclusive, the stud S is of usual contour and construction and has the usual flange S. The portion of the stud below the flange S is provided with a flattened elongated locking head S formed integral with said stud and preferably -provided on its top face with a pair of oppositely disposed sockets C.

The stud holding plate P, which is adapted to be disposed upon the side of the material opposite to the stud S, has a central I elongated opening P preferably of the shape shown, through which the locking head S of the stud can pass in one position only, so that when said head S is passed through said plate the parts can be locked by relative rotary movement thereof. Preferably said plate P has a pair of oppositely disposed projections or bosses D which cooperate with the sockets C provided in the locking head S In securing the stud member to material the stud S and retaining plate P are disposed onopposite sides of the material and the locking head S is passed into and completely through the opening P of the holding plate. The stud and plate are then relatively rotated 90 from the positi n shown in Fig. 6 to the position shown in Figs. 8 and 9, whereupon the locking head is moved to a position transverse of the opening P so that the parts are locked and yieldingly held in locked relation by entrance of the projections D into the sockets C.

-To remove the stud member, the stud S and its retaining plate P are pressed toward each other until the projections D are free to leave their sockets 'C permitting relative rotation of the stud and plate to a position 90 from looking position, whereupon the locking head S is free to pass out of the retaining plate.

Preferably the socket retaining plate B is provided with an annular ridge B of substantially the height of the ears A when in locked position as shown in Fig. 4 so that the bottom of said retaining plate presents a substantially smooth surface. The said retaining plate P has a similar flange P It will, I believe, be clear that a fastener member made in accordance with my invention as above described can be readily affixed to material by persons without experience in the particular work, and without the employment of special tools. It will also be apparent that the fastener can be readily removed from the material as oocasion may require.

I claim:

1. A fastener member comprising two parts adapted to be disposed on opposite sides of material, one of said parts having a single, central opening and the other of said parts having a locking head adapted to be passed through said opening and thereafter to be turned transverse thereof and to engage the outer face ofsaid first named part to lock said parts in operative position.

2. A fastener member comprising two parts adapted to be disposed on opposite sides of material, one of said parts having a single, central opening and the other of said parts having a locking head adapted to be passed through said opening and thereafter to be turned transverse thereof and to engage the outer face of said first named part to lock said parts in operative position, and means yieldingly to retain said parts in locked relation.

3. A fastener member comprising two parts adapted to be disposed on opposite sides of material, one of said parts having an opening and the other of said parts having a depending annular skirt provided with a locking head, said head ada ted to be passed through said opening an thereafter to be turned transverse thereof to lock said parts in operative position.

4.

5. A fastener member comprising two parts adapted to be disposed on opposite sides of material, one of said partshaving an opening and the other of said parts having a depending annular skirt provided on its bottom edge with a plurality of upturned ears forming a locking head, said ears adapted to be passed through said opening and thereafter to be turned transverse thereof to lock said parts in operative position.

6. A fastener member comprising two parts adapted to be disposed on opposite sides of material, one of said parts having an elongated opening and a plurality of slots, and the other of said parts having a depending annular skirt provided on its bottom edge with a plurality of upturned cars forming a locking head, said head adapted to be passed through said opening and thereafter to be turned transverse of naeaose said opening to lock said parts in operative position and said ears adapted to enter said slotsyieldingly to retain said ears in locked relation.

7. A fastener member comprising two parts adapted to be disposed 'on opposite sides of material, one of said parts having an elongated opening and a pair of oppositely disposed slots, and the other of said parts. having a depending annular skirt provided on its bottom edge with a pair of oppositely disposed upturned ears forming an elongated head, said head adapted to be passed through said opening and-thereafter to be turned transverse of said opening to'lock said parts in operative position, and said ears adapted to enter said slots i'ieldingly to retain said head in locked reation.
